Lucius Malfoy is the father of Draco and husband to Narcissa Malfoy. He is a Death Eater and all around baddie in the Harry Potter books though in the last installment of the series, the Deathly Hallows, Lucius' pureblood ideals seem to take a back seat to protecting his family. In the second book, he was responsible for getting Tom Riddle's diary into Ginny Weasley's hands and thus reopening the Chamber of Secrets. He was a high ranking Death Eater in Voldemort's inner circle until he screwed up and got thrown into Azkaban prison for the Department of Mysteries debacle. Lucius is known for his wealth and influence in the Wizarding community despite his prejudice against Muggle Borns like Hermione Granger. He is portrayed by Jason Isaacs in the Harry Potter films.

Hermione: Wow, that Lucius Malfoy is a real fox! Too bad he's such a prejudiced prick and would probably Avada me if I offered to polish his broomstick...
